- Q:The chemical composition of silica brick and its physicochemical index?
- Brick refers to the refractory products in more than 93% of the content of SiO2
- Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
- Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.
- Q:Semisilica brick interpretation
- Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.
- Q:Common bond brick?
- When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.
- Q:Physical solid waste disposal
- The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
- Q:The difference between clay refractory bricks and refractory brick in the application.
- Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
- Q:Can iron oxide be used as refractory material?
- Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.
- Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
- The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.
- Q:What is the main material of silica brickIt's common, the kind we see so often!
- More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.
- Q:What is acid refractory?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
